Tyler Smith 2e7dce8268 Adds extensible header functionality
This change is to introduce a flexible mechanism for projects to
add content to horizon's navbar.
- Introduces a new plugin file variable called ADD_HEADER_SECTIONS,
  which will take a list of views.  These are template views that
  will be used to render individual header sections.
- There is a new view in openstack_dashboard/views.py to cycle
  through these added views and combine them into the complete
  header to be added to the navbar.
- This view is queried by newly added javascript after page load.
  On response it is inserted into the page's navbar.
  If more than one header is present, the first will be shown in
  the navbar, while the rest are added to a drop-down menu.
- The currently displayed header can be changed by clicking on a
  new header in the drop-down; this is stored in a cookie to
  persist the selection between pages.
- Unit tests were modified/added to verify the new plugin entry
  can be parsed successfully and the main header view can parse
  a plugin's view successfully
